HEADLIGHT'.

SPECIFICATION forming part of Letters Patent No. 664,418, dated December25, 1900. Application iiled October 1'7, 1899. Renewed October 18,1900;' Serial No. 33,450. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, FRED B. LASH, a citizen of the United States,residing at Farmersburg, in the county of Sullivan and State of Indiana,have invented certain new and useful Improvements in Headlights; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in theconstruction and combination of parts necessary to provide a lightdesigned, primarily, for use as a headlight upon a locomotive, though itwill be found desirable and useful for all of the various purposes forwhich a concentrated light of great brilliancy may be used.

The prime object of my invention is to provide a reiiector for myheadlight which will have great capacity to concentrate or reflect alight and direct it to a given point.

A further object is to provide reliably-eilicient means by which thereflector may be reliably adjusted and securely held in its operativeposition without liability of its exterior coating of Quicksilver or thelike being injured or without fear that the reflector will becomebroken.

A further object of my invention is to provide means for quicklygenerating a gas from gasolene or similar oil, as will be hereinafterfully set forth, the details of my inventionbeing illustrated in theaccompanying drawings, in which- Figure 1 isa central vertical sectionof a headlight provided with a portion of the tubl ing comprised in myinvention and showing the relative location of the burner, chimney, andcontiguous parts. Fig. 2 shows a central vertical section of a portionof the oilconveying pipe shown in Fig. 1 supplied with means to quicklygenerate gas "from the oil. Fig. 3 illustratesa transverse section ofthe reflector and its cushion of rubber and exterior casing, andillustrating another disposition of the gas-conveying pipe from theposition thereby occupied in Fig. 1. Fig. 4 is a central longitudinalsection of another form of r reflector from that presented in Fig. 1.

Fig. 5 illustrates a varied construction for the conveyerpipe.

For convenience of designation the several parts of my invention andtheir coperating features Will be referred to by numbers, of-

Which 1 illustrates the exterior casing of the headlight, which may beformed in any preferred Way and provided with the usual vent 2, designedto permit the escape of the products of combustion, as is usual, itbeing understood that the body of the headlight thus provided may beatt-ached at any desired point, as upon the bracket 3 of a locomotive,by means of bolts passing through the base, section 4 or otherwise.Within the housing thus or otherwise provided I dispose my improvedreflector, Which consists of the reflector proper, 5, formed preferablyof glass and molded and shaped as illustrated in Figs. l or 4, orotherwise, as may be deemed productive of the best results, and theoutside thereof is coated in the usual Way with a quicksilver compounddesigned to make this portion of the reflector entirely impervious tolight, and thereby enable the reflector to concentrate the rays of thelight and direct the same to any desired point.

An integral radial fiange 6 is formed upon the rim of the reflectorproper, designed for the purpose of holding the reflector in an adjusted position, as by means of bolts 7, passing through the contiguouswall S of the housing, as clearly shown in Fig. 1.

After the reflector proper has been provided with a coating ofquicksilver or its equivalent itis fitted with the jacket 9, which isdesigned to cover all exterior parts of the reflector from the flange 6inward, said jacket being preferably formed of rubber, though otheryielding material may be found desirable, the object in thus providingthis covering or jacket being to cushion the reflector proper and holdthe same securely in position without liability of injuring the surfaceformed by the quicksilver dressing, inasmuch as the rubber jacket willcling tightly around its exterior coating from .becoming injured,

' tween the outer casing and the reiiector.

In order to securely inclose the reflector proper and its cushion ofrubber, I provide the exterior casing 10, formed of some suiti ablesheet metal shaped so as to snugly it said parts, and in order that thecasing may be held into cooperative relationship with said interiorparts I form thereon a radial flange 11, designed to cooperate with theflange 6 upon the reector proper, and it is clear that by reference toFig. 1 the bolt 7, after passing through the wall 8, is extended throughsuitable aperturesin the anges 6 and 11 and secured by a suitable nut,and thereby locking all of said parts closely together andinsuring thatthe reflector, with its outer casing, will be disposed within thehousing l in a proper Way to coperate with the lamp 12, which may be ofany preferred construction and is preferably provided' with the usualmantle 13, designed to render the light incaudescent.

It will be understood that a suitable lens 14 is secured to the outsideof the wall 8 in such position that it will coperate with the reflector,the said lens being held in position in any preferred Way, as by theextension or casing 15, secured to the wall 8 in any preferred way,preferably by hinges, so that said lensmay be moved out of the way torender the lamp or the interior of the refiector readily accessible, asfor purposes of repair or for cleansing said parts.

Suitable apertures 16 are provided in the reiector and its outer casingsdesigned to permit proper draft to the lamp and to allow the chimneythereof to extend upward into the housing, as shown in Fig. 1, and inorder to support the lamp in its adjusted operative position I provideat a suitable point beneath the lower aperture 16 the bracket 17, towhich I secure the exit or vent portion 18 of the conveyer-pipe 19. Theworking parts of the lamp are secured to the end of the vent-pipe 18 inany preferred way, as is usual.

The conveyor-pipe 19, as will be seen by reference to Fig. 1, extendsupward to a point above the re Hector, where it terminates in theinwardly-directed right-angled extension 20,

having the flared end 21 designed to receive the free end of thesupply-pipe 22, which extends upward to the oil-tank 23 located at anyVpreferred point upon the exterior of the housing 1, the supply of oilfrom said tank being regulated or controlled by the valve 24.

end 21 of the conveyer-pipe 19, and by such pipe delivered to the lampthrough the Vent 18.

In order to insure that the oiljemployed as fuel shall be readilyconverted into a gaseous state, I dispose with-in the supply-pipe anauxiliary flue, consisting of the U-shaped pipe 26, having the flaredreceiving end 27 and the flared terminal 28, it being understood that inorder that the auxiliary tube or flue 26 may be readily introduced.within the supply-pipe the latter is made in sections, as

'indicated by the joints 29 and 30, thus enabling said parts to be verycheaply man ufactured and quickly assembled in their respectiveoperative positions. The construction illustrated in Fig. 2 is upon aslightly-enlarged scale, it being understood that all of the parts shownin said View are wholl y inclosed in the housing 1. By this arrangementit is therefore obvious that the vent or terminal 28 will discharge anyheat productsinto the housing,

p from whence they will escape through the vent 2. The heat productsfrom the chimney will enter the flared end 27 and pass through the U-shaped pipe 26, and from thence into theupper'portion of the housing 1,from whence they will escape through the vent 28, thus practicallyincreasing the heating-surface applied to the oil, inasmuch as the heatfrom the `lamp will not only pass through the auxiliary flue thusprovided but will also act upon the .exterior of the supply-pipe withinwhich said line is disposed.

In Fig. 3 I have shown that the conveyerpipe 19 may be disposedlaterally `or to .one side of the position occupied by the lamp insteadof to the rear thereof, as'shown inFig. l, it being understood that theposition of said pipe may be determined by expediency.

In Fig. 5 I have illustrated still another construction which may beadopted in forming the supply-pipe, wherein it will be observed that acoil-pipe formed out of said supplypipe is disposed immediately over theflue and consists in so shaping said pipe that a series of outer coils3l is formed, and after a sufficient number of said coils have beenprovided the'end of the pipe is turned down lthrough the center of saidcoils, as indicated Vrable permanent character and that the severalparts thereof may be very cheaply man- It will be understood that thedispositionE of the supply-pipe 22 shall be so made that it will beplaced immediately over the end of.. the chimney 25 in order that theheat from; `the lamp Will result in the generation of gas` from the oil,which gas as it leaves the sup- Vply-pipe 22 will 'be' conducted intothe flared:`

substantial equivalent thereof, and I do not therefore wish to be connedstrictly to the exact showing herein made.

IOO

IIO

The cushion 9, it is obvious, will absorb the blows' and jars incidentto the usage of 1my improved reector upon a locomotive or other movingmechanism, thereby -insuring that the reflector proper, formed of glass,will be fully protected.

Having thus fully described the construction of my invention, what Iclaim as new, and desire to secure by Letters Patent, is

l. As an improvementv in headlights, the combination with a suitablehousing, of a reflector disposed within said housing, and having aradial flange; a metallic casing fitting said reiector; a cushion ofrubber or the like interposed between said casing and reflector; asuitable lamp mounted within the same and having its chimney extendingthrough said reflector and casing; a conveyer-pipe coperating with saidlamp, in combination with a supply-tube coperating with saidconveyertube and having an auxiliary Hue extending through a portion ofits length whereby the heat of the chimney will be directed through saidfiue and thereby more quickly transform the oil into gas in the manner'specified and for the purpose set forth.

2. The herein-described headlightcompris ing an exterior housing 1; areiiector proper having a jacket of rubber and an exterior casing ofmetal disposed within said housing and means to hold said parts in anadjusted position, in combination with a lamp mounted within saidreiector and an oil-supply pipe having an auxiliary iiue disposed iu theinterior thereof whereby the oil will be more quickly vaporized by theheat of the lamp passing through it in the manner specified and for thepurpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
